Navigating Singapore’s business registration process begins with selecting the correct SSIC code—your Singapore Standard Industrial Classification code. This 5-digit, hierarchical code (based on ISIC but tailored by the Department of Statistics Singapore) classifies your company’s primary economic activity. The SSIC code isn’t just bureaucracy; it directly affects licensing requirements, eligibility for government grants, tax incentives, and loan approvals. Meanwhile, ACRA (Accounting and Corporate Regulatory Authority), Singapore’s Registrar of Companies, ensures compliance under the Companies Act, making correct SSIC code selection critical from the outset.
Choosing the right SSIC code impacts your business in multiple ways, including statistical tracking, government reporting, and long-term corporate strategy. Common errors, such as mismatched codes, can delay applications and result in fines. Whether you run a café (SSIC code 56112) or a fintech startup (SSIC code 63120), understanding SSIC codes in Singapore, their importance, how to search for them, and how to update them is crucial for compliance and smooth operations.
What Are SSIC Codes in Singapore?
SSIC codes reflect your principal revenue-generating activity and are used to aggregate industry data for both government and market analysis. Each SSIC code consists of up to five digits and follows a hierarchical structure:
- 21 broad categories (A–U)
- 3-digit divisions
- 4-digit groups
- 5-digit classes
For example:
- 56: Food and beverage service activities
- 561: Restaurants, cafés, food courts
- 56112: Cafés
This hierarchy allows precise classification and helps businesses benchmark against competitors. While ISIC provides a global classification, Singapore’s SSIC codes are tailored for local nuances and are regularly updated to accommodate emerging industries.
Authorities in Singapore use SSIC codes to:
- Track economic trends and manage statistical analysis
- Determine licence and regulatory requirements
- Qualify businesses for grants, tax incentives, and subsidies
- Evaluate eligibility for loan or grant applications
SSIC codes are essential for Singapore’s business ecosystem, helping authorities monitor and regulate industries while ensuring businesses are correctly aligned with national policies. Regular updates to SSIC codes reflect changes in the economy, adoption of international standards, and new business activities.
Additionally, SSIC codes assist in:
- Determining if a company requires additional business licences
- Assessing eligibility for corporate tax benefits

How to Input the Right SSIC Code
When registering your business, choose the SSIC code that aligns with your primary business activities. For example:

Maximum allowed: 2 SSIC codes. Choosing the right codes reduces administrative overhead and ensures proper classification for licences, grants, and tax purposes.
